Patent CA-1037132-A (CA)

IPC: H03K4/56

Abstract: ABSTRACT           A sawtooth wave form generating circuit in which the amplitude of the sawtooth wave form is automatically maintained at a constant value by passing the same through a variable gain amplifier, measuring the amplitude of the sawtooth wave form at the moment when it reaches its maximum value, comparing such amplitude with that of a standard voltage and adjusting the gain of the amplifier accordingly.          This is done through the use of a capacitor which is charged upon the occurrence of the same pulse which discharges the capacitor of the sawtooth wave generator.  The capacitor controlling the gain of the amplifier is charged under the control of a comparator amplifier having one input from the output of the variable gain amplifier and the other from a source of standard voltage.  The sawtooth wave generator is particularly applicable for use in measuring phase differences between two events recurring at a variable repetition rate such as encountered in automobile ignition diagnosis.

Abstract: ABSTRACT OF THE DISCLOSURE A hide-puller includes a pair of transversely spaced, endless, flexible members which define a continuous, vertical path having a forward descending reach and a rearward ascending reach.  A horizontal reaction member is secured to, carried by and spans the flexible members and is advanced therewith along the continuous path.  A carcass to be stripped of hide is sus-pended, head-end down, from an overhead support forwardly of and adjacent the descending reach and a stationary anchor member is disposed intermediate of the reaches for securing a loosened, tail-end-adjacent flap of the hide, whereby the reaction member engages and imparts a downward, hide-pulling motion to the hide intermediate of the anchor and the carcass as the reaction member advances in the downward reach.

Abstract: ABSTRACT OF THE DISCLOSURE     An air scrubbing device comprising a hollow closed housing having an inlet port and an outlet port to permit the passage of compressed air therethrough.  An air scrubbing cham-ber is provided within the housing and contains a plurality of spherical glass elements for obstruction with the normal pas-sage of the compressed air through the housing.  The spherical glass elements cause turbulence of the compressed air whereby a substantial portion of undesirable particles contained in the air will be ejected from the air and deposited on the surface of the spherical elements.  A valve is provided to cause a "blow off", in the reverse direction to the normal passage of air, of the deposits of undesirable particles from the spherical elements and the chamber and to evacuate it from the housing.

Abstract: ABSTRACT OF THE DISCLOSURE           A flow block and bushing assembly employing an orifice plate having a perforated drawing area with a planar undersurface against which bulk gas flow is directed for cooling and fiber attenuation purposes.  The flow block is comprised of an interior layer of highly glass corrosion resistant material, such as zircon, and an exterior layer of highly thermal shock-resistant material.  A flow passage extends through both of said layers and is lined with platinum foil. The bushing assembly is removably secured beneath the flow block and comprises a body of refractory material having a flow chamber extending therethrough in alignment with the flow passage.  The flow chamber is lined with a platinum foil lining and the orifice plate is joined to the lining and extends over the lower end of the chamber.  The orifice plate is reinforced by ribs integrally joined to and extending across the upper surface of its perforated drawing area and a perforated reinforcing plate is integrally joined to the ribs in spaced parallel relationship to the orifice plate.  Electrodes are joined to the orifice plate to either side of the drawing area whereby electrical current may be passed through the orifice and reinforcing  plates and flow chamber walls to effect the resistance heating thereof.  Bulk gas flow is provided by a nozzle having a plurality of individual inlet conduits communicating with a common elongate discharge passage.  An adjustable manifold communicates with the inlet conduits of the nozzle to provide for the selective supply of gas thereto and the nozzle is adjustably mounted so that its angular orientation relative to the undersurface of the drawing area may be varied.

Abstract: ABSTRACT OF THE DISCLOSURE     The specification describes an arrangement for measuring and controlling the thickness of optically active thin layers during formation in vacuum coating installations   The arrange-ment operates by detecting the reflection and transmission behaviour of layer thicknesses between fractions and multiples of the wavelength of an essentially monochromatic measure-ment light.  The coating process is interrupted when a pre-determined layer thickness has been obtained.  The arrangement consists of a measurement light source for emitting a focused measurement light beam, a chopper device, a beam divider arranged at an angle of 45 degrees on the axis of the measure-ment light beam with that part of the measurement light beam passing behind the beam divider being directed on the measure-ment object, a measurement light receiver provided with a monochromator, a differentiation device for the measurement of signal and an interruption device for the coating process.          The axis of the measurement light beam emitted from the light source is orientated towards the measurement object and a reference light receiver independent of the optical properties of the measurement object is associated with the measurement light beam.  The output signal of the reference light receiver is mixed with a trigger stage for a phase-sensitive photometer amplifier.  The signal is fed to a compensation circuit for the equalization of brightness variations in the measurement light source.

Abstract: ABSTRACT      A free-standing, prefabricated, knock down, readily assembled and disassembled, relocatable vertical wall or space divider.  Such wall dividers are useful for partitioning build-ings and/or office complexes. The wall is made up of a plur-ality of individualized and decorative flush panel units which are interchangeable and which are adapted to be readily inserted within quadrilateral openings delineated by a novel wall frame and locked into place by hidden spline members that are mounted in the wall frame for translatory movement.  The wall frame is fabricated in a novel assemblage of unique components which can present either a metallic or wooden exterior finish surface. The configuration of the wall frame components provides for lateral walls to extend outwardly not only at modular locations but also from any other desired location by use of novel adap-ters.  The panels may be removed, redecorated and replaced as needed.  Shelving or other appurtenances are attachable to the hidden spline members. The entire wall panel and/or divider is readily relocatable when it is desired to re-arrange, enlarge or change a given floor space.
